Slide10

Wearing Hardhats Backwards

Is it OK to wear a hardhat backwards?

Only if marked with a "reverse donning arrow;” it can be worn frontward or backward in accordance with the manufacturer's wearing instructions. Manufacturers do not recommend that workers wear standard hard hats backwards unless it is necessary for certain job applications, such as welding, where a mask is required. OSHA clearly specifies that workers must wear their hats the way they were designed to be worn, unless the manufacturer states a hat can be worn backward.

Slide11

Hearing/Ear Protection

Earplugs - come

in a variety of sizes, shapes and materials. Must be prepared and inserted correctly. Earmuffs – Normally consist of rigid, molded plastic ear-cups that seal around the ear using foam or fluid-filled cushions and are held in place with metal or plastic headbands.

11

Slide12

More Hearing Protection

Semi-Aural

Devices – consist of pods or flexible tips attached to a lightweight headband. Provides a compromise between earmuffs and earplugs. Can be worn in close quarters, easily removed and replaced and conveniently carried when not in use. One size fits the majority of users. Fit is not compromised by safety glasses or hard hats.

Noise

Power mower at 3ft = 107 dB Snowmobile, motorcycle = 100 dB

Power saw at 3ft = 110 dB Sandblasting, loud rock concert = 115 dB (Pain begins 125 dB) Pneumatic riveter at 4ft = 125 dB (Even short-term exposure can cause permanent damage. Loudest recommended exposure WITH hearing protection is 140 dB) Jet engine at 100ft, gun blast = 140 dB (Death of hearing tissue is 180 dB) Loudest sound possible 194 dB

13

PPT-029-04

Slide14

Using Hearing Protection

Generally, the louder the noise, the shorter the exposure time before you have to use hearing protection.

The requirements for noise reduction (including hearing protection) begin: - When noise exposures are at or above 85 dBA time-weighted average, or - There are impulse noise sound pressure levels of

140 decibels peak.

14PPT-029-04

Slide15

Using Hearing Protection

Hearing protection must be made available to employees if they are exposed to noise between 85-90

dBA anytime during their work shift.Hearing protection MUST be used if the exposure level is 90 dBA or higher for any duration during their shift.

15

PPT-029-04

Slide16

Hand Protection

Hand protection should be used when workers are at risk of injury to their hands or arms.

Example: material handling, chemical use, welding, mechanical jobs, electrical work, cutting materials.

16

PPT-029-04

Slide17

Correct Gloves for Job

Need to evaluate the job/task being done and provide the best protection.

Cloth or leather gloves should not be used for protection against chemical hazards (use neoprene, nitrile, rubber, etc., depending upon chemical). Surgical gloves are not used on electrical jobs (use heavy duty rubber/insulated labeled for electrical use). Cloth gloves should not be used for material handling (use leather gloves).

Slide22

Respiratory Protection

OSHA 29CFR Part

1910.134, Respiratory Protection Respirators shall be provided when necessary to protect the health of employees from breathable hazards. “In the control of those occupational diseases caused by breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors, the primary objective shall be to prevent atmospheric contamination. This shall be accomplished as far as feasible by accepted engineering control measures.”

22

PPT-029-04

Slide23

Respiratory Protection

Respirators

shall be used in the following circumstances:Where exposure levels exceed the permissible exposure limit, or PEL, during the time period necessary to install or implement feasible engineering/work practice controls.In regulated areas.Where

employer has implemented all feasible engineering and work practice controls and these are not sufficient to reduce exposures to or below the permissible exposure limit.

23

Slide24

Respiratory Hazards

There are two main types of respiratory hazards:

Oxygen DeficiencyAirborne Contaminants

24

PPT-029-04

Slide25

Respiratory Hazards

Oxygen Deficiency

Air is composed of approximately 21% oxygen,78% nitrogen and other trace components. If the oxygen level is less than 19.5 % then you are in an oxygen deficient environment.Only atmosphere supplying PPE can be used when working in an oxygen deficient environment

25

PPT-029-04

Slide26

Respiratory Hazards

Airborne

contaminants include:Dusts (e.g., from sawing or grinding)Mists (e.g., from spray painting)Vapors (gaseous forms of a liquid)Fumes (e.g., from welding operations)Gases (e.g., nitrogen, methane)Biological (e.g., bacteria & viruses)

26

PPT-029-04

Slide27

Permissable Exposure Limit

An example of how to apply the PEL:

The OSHA PEL for asbestos = .1 asbestos fiber/Cubic Centimeter (CC) of air.Collection of air samples & laboratory analysis is used to measure asbestos fibers in the work area.If the analysis determines that equal to or greater than .1 fiber/CC of air exist then a respirator must be worn.Respirator selection is based on the level of asbestos fibers identified.

27

PPT-029-04

Slide28

Types of Respiratory PPE

Two general categories:

Air-purifying respirators Remove contaminants from air through chemical or mechanical means.Atmosphere-supplying respirators Self-contained breathing apparatus,

or SCBA, and airline Equipment or SARs.

28

PPT-029-04

Slide29

Assigned Protection Factors

“The workplace level of respiratory protection that a respirator or class of respirators is expected to provide.”

Employers must use the OSHA assigned protection factors listed at 29CFR 1910.134 (d) at Table 1.

Slide34

Initial Medical Evaluation

Employee must first receive a medical evaluation from a physician or other licensed health care professional who will determine if they can

wear a respirator.Immediate supervisor must obtain a written recommendation from a health care professional on whether or not the employee is medically able to use the respirator.

34

PPT-029-04

Slide35

Fitting the Respirator

The fit of a respirator face piece to ensure a good seal is extremely important . A secure fit means the difference between life and death!

Since most face pieces fit only a certain percentage of people, it is important that face pieces are tested for each potential user.

35

PPT-029-04

Slide36

Factors Affecting Fit

Facial features such as beards, hollow temples, prominent cheekbones, dentures or missing teeth.

Recent jaw surgery.Chewing of gum or tobacco.

36

PPT-029-04Under OSHA, could this guy wear a tight fitting respirator?

No, due to excess facial hair.

Slide37

Initial Fit Testing

Employees must be fit tested before initial respirator use and then

annually thereafter.Two types of tests: qualitative and quantitative. Qualitative – user determines if he/she can smell testing agent being used.

Quantitative – instruments detect agent.

37

PPT-029-04

Slide38

Written Respiratory Protection Program

OSHA requires that employers establish a written respiratory program documenting each hazard, site by site, based on a work site survey and evaluation.

Written program should spell out site-specific procedures that will be implemented to reduce dangers including:Procedures for selecting respiratorsMedical evaluation of employees required to wear respiratorsFit-testing proceduresProcedures for proper use of respirators in all situationsProcedures and schedules for cleaning, disinfecting,

storing, etc.Training Program evaluation procedures

38

PPT-029-04

Slide39

Summary - PPE

PPE should be used

last in a series of protective measures, following engineering and administrative controls.PPE should not be arbitrarily issued; employees should be given the correct equipment that fits properly.PPE should be in serviceable condition and stored in an area where it cannot be damaged or exposed to the elements.Employees who are given/use PPE should receive appropriate training in the use of that equipment, and training should be documented.Hazard assessments should be performed and documented.
